How to Maintain a PVC Foam Board Cutting Machine?

The PVC foam board cutting machine is a CNC machining system consisting of a high-rigidity gantry and a variable-frequency spindle. It features an integrated vacuum table and multi-layer staggered air circuits with independent control zones. The X/Y axes utilize a dual-servo drive anti-backlash mechanism to eliminate contour errors caused by backlash.

Daily Maintenance Tips:

Before operating the PVC foam board cutting machine, clean the guide rail guards and use a dedicated dust collection device to prevent dust. Apply antioxidant grease daily to the spindle taper to prevent tool lock caused by the oxide layer. Perform reverse pulse cleaning when the vacuum filter pressure differential exceeds the safety threshold.

Preventive Maintenance Measures:

Check the drive belt tension of the PVC foam board cutting machine weekly. Replace the entire pulley set if the preload loss exceeds tolerance. Clean the ball screw quarterly for heavy-duty grease, removing old grease and abrasive particles before greasing. Wipe the scale monthly with a dust-free cloth in one direction. Do not use organic solvents to clean the scale area.

How should I address melt marks on the cut surface?

First, check the cooling nozzles on the PVC foam board cutting machine for blockage. Ensure the airflow covers the entire cutting area. Reduce the spindle speed and increase the feed rate to shorten heat transfer time. Replace the cutting tool with a nano-coated material to enhance heat dissipation. Verify that the material density exceeds the specified value and adjust the cutting parameter database.
